This sign could be compatible with an upper respiratory tract inflammation/infection or possibly to a chronic rhinitis (inflammatory, allergic, infective). A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

    Willow's sneezing increase this time of year could be due to all of the extra irritants and allergens in the air from pollens, trees, and grasses. If she has yellow or green nasal discharge, this could indicate infection. However, if her discharge is clear and minimal, infection is unlikely. Consider discussing antihistamine medications with Willow's vet, because these can provide some minimal benefit in some cases.

    Reverse sneezing is most commonly caused by something they inhale that irritates the nasal passages and causes dripping down the back of the throat. Sneezing can be caused by allergies or an upper respiratory infection or even an object that was sniffed up the nose (like a grass seed or a piece of grass that is lodged inside the nose). If the sneezing continues or there starts to be discharge from the nose, I would definitely recommend taking him to a veterinarian for evaluation.

    Both sneezing and reverse sneezing can be a sign of allergies, an upper respiratory infection or even something stuck up the nose. If the sneezing seems extreme or you’ve noticed any nasal discharge you should have your vet examine Negan Carlos.
